Homemade 63 Watt Solar Panel

Step 4 Solder the Bus Bar

Soldering bus bar is much easier than soldering solar cells. You also need to solder tabbing wires to the untabbed dots on first solar cell of each row. You need to take the negative wires and attach them to the bus bar and then take the positive wires and attach them to the bus bar. Then on the side of that there will be another separate bus bar that is the negative side. Do that on the opposite side and then test for 18 volts. Now solder your positive and negative wires to the bus bars. Now drill holes and run your wires through them.

Rather confusing - you just stated that you connected your positive and negative tabs to the same bus bar... You should (have) take(n) a picture of the overall layout - and indicate where your positive & negatives are going, justa  thought.

You connect each cell in a ceries wiring so the cells are connected from +  to  -.
[-+] [-+] [-+] [-+] [-+] [-+] [-+] [-+] [-+]       ([-+] solar cell)    
each cell only puts out .5  volts so this type of wiring gives you a higher voltage.

Yeah, I guess I said that wrong. I will try to get a picture explaining it better. Thanks for pointing that out.
